RAILROAD-SWITCH.

Application filed May 29, 1917.

To all whom it may concern:

Be it'known that I, EDMUND CRAnnooK JONES, a citizen of the UnitedStates, re siding in Cincinnati, in the county of Hamilton and State ofOhio, have invented new and useful Improvements in Railroad- Switches,of which the following is a specification.

An object of my invention is to produce an improved railroad switch inwhich the wheels of cars may pass the intersection of the crossing railsof a switch with no jarring or hammering action thereon, there bycontributing to the greater smoothness of passage of the cars over therails of switches as well as substantially eliminating the wear andloosening of the rail joints at intersecting points of switch rails.

This and other objects are attained in the switch herein described andillustrated in the drawings in which Figure 1 is a plan view of a switchembodying my invention, showing the switch elements set for passage ofcars along the main line of track.

Fig. 2 is a plan view of my improved switch, showing the switch elementsset for passage of cars from the main track onto a side track.

Fig. 3 is an inverted plan view of my improved switch, showing moreclearly the operating mechanism of my switch, the parts thereof beingset to retain the switch elements in the positions disclosed in Fig. 1.

Fig. 4 is a transverse sectional view taken on the line -l l of Fig. 3,of the frog of my improved switch, upon an enlarged scale.

Fig. 5 is a sectional view of a joint between links and levers in myimproved switch construction, and taken on the line 55 of Fig. 2, uponan enlarged scale.

Fig. 6 is a transverse sectional View taken on the line 66 of Fig. 1,and upon an enlarged, scale.

My improved switch is disclosed as connecting a side track consisting ofrails 7 and 7 with a main track consisting of rails 8 and 8, the usualshifting rails 9 and 9 being provided for diverting cars from the mainto the side track or from the side to the main track. Located at theintersection of the inner rails 7 and 8 of the side and main tracks is afroglO embodying the principal feature of novelty of my improvedconstruction and consisting of a turn table 11 of cylindrical shape andof heavy construc- Specification of Letters Patent.

tion having a groove 12 formed therein for the passage of the flanges ofcar wheels therethrough. This turn table is pivotally mounted in asocket formed by flanges 13 formed on a plate 14 to which is bolted orotherwise secured the converging ends of inner rails 7 and 8 and theconverging ends of shifting rails 9, the plate being in turn secured tosleepers 15 and 16 of the tracks. The turn table is retained in thesocket by means of a plate 17 which is secured to plate 1-1 as disclosedin Fig. 4 and which cooperates with an operating crank 18 which is heldin position upon a tapered extension 19 of turn table 11 by means of aWasher 20 and lock nut 21.

Between the convergent and divergent ends of shifting rails 9 and 9, isa plate 22 which is secured to track sleepers 23 and 24. Upon a taperedextension 25 of this plate a swinging arm 26 is pivotally mounted, awasher 27 and adjustment nut 28 being provided for maintaining the armin position thereon. One end of this arm is connected with a link 29which connects itwith crank 18 of turn table 11. Located at thedivergent ends of shifting rails 9 and 9 and pivotally mounted upon aplate 30 which is secured to a track sleeper 31, is a bell crank lever32, the longer arm of which is con- 7 nected with a link 33 whichconnects it with the opposite end of arm 26. The opposite end of bellcrank 32 to which link 33 is pivotally connected is pivotally connectedwith a coupling 34 which is secured to brace rod 35 which cooperateswith a brace rod 36 in holding the shifting rails in proper spacedrelation. This coupling 3 is connected with a rod 37 extending fromswitch stand 38 which is provided for throwing the switch.

Each of the joints between the links and the levers and between thelinks and the cranks is constructed somewhat as shown in Fig. 5 in whichbell crank 32 is provided with a conical extension 39 upon which awasher and lock nut 40 are mounted for retaining the end of link 33 inposition thereon. Figs. 4L and 6 also illustrate the manner of makingconnections, pivotal and otherwise, for the purpose of facilitating thetaking up of lost motion existing in the operative mechanism of theswitch, so that groove 12 of turn table 11 will be brought to registeraccurately with the rails when turned to either of the positionsdisclosed in Figs. 1 and 2, by the shifting of rails 9 and 9 to therespective positions disclosed in these figures.

Having thus described my invention What I claim is A railroad switchcomprising a pair of shifting rails located between the outer rails oftracks to be connected, a rail shitting mechanism, a turn table locatedat the point of intersection of the inner rails of the tracks to beconnected and consisting 1": a socket secured to the track sleepers, agrooved cylindrical member rotatively mounted in the socket and havingan extension from the bottom thereof, a lever mounted on the extension,and a system of links and levers connecting the first mentioned lever,the shifting rails and the mechanism, the points of connection of thelevers With the elements of the switch and of the levers with the links,being tapered to permit the taking up of lost motion between themechanism, the turn table and the rails.

In Witness whereof, I afiix my signature in the presence of twoWitnesses.
